I must share this quote by Gerd Puin, a German scholar and the world’s foremost authority on Qur’anic paleography, the study and scholarly interpretation of ancient manuscripts. He is a specialist in Arabic calligraphy:

My idea is that the Koran is a kind of cocktail of texts that were not all understood even at the time of Muhammad. Many of them may even be a hundred years older than Islam itself. Even within the Islamic traditions there is a huge body of contradictory information, including a significant Christian substrate; one can derive a whole Islamic anti-history from them if one wants. The Qur’an claims for itself that it is ‘mubeen,’ or clear, but if you look at it, you will notice that every fifth sentence or so simply doesn’t make sense. Many Muslims will tell you otherwise, of course, but the fact is that a fifth of the Qur’anic text is just incomprehensible. This is what has caused the traditional anxiety regarding translation. If the Qur’an is not comprehensible, if it can’t even be understood in Arabic, then it’s not translatable into any language. That is why Muslims are afraid. Since the Qur’an claims repeatedly to be clear but is not—there is an obvious and serious contradiction. Something else must be going on.

I will leave it to you to decide whether the words of the Qur’an is the true word of Allah for which it is justifiable to murder and oppress…
